Sea Cresswell has provided a solution to this in an earlier post. In essence set your Solid Edge Options > Helpers > Command Buttons to "Increase buttons on Command Ribbon 2X"
Everything looks smaller on your Macbook because it has a very high screen resolution (dots per inch). This is why Solid Edge provides this control it allows readability on high resolution small screens.
From apple "All 15-Inch Retina Display MacBook Pro models (A1398) have a 15.4" color display with 2880x1800 native resolution at 220 ppi and all 13-Inch Retina Display MacBook Pro models (A1425, A1502) have a 13.3" color display with 2560x1600 native resolution at 227 ppi."

I notice that in another post you asked about Solid Edge on native Apple. This is very unlikely as there is little real demand as evidenced by the fact that none of the major CAD vendors have apple versions of their product. Siemens (UGS) had in the past ported their mainstream NX product to Apple but I understand that this is no longer supported.
